specific Embodiment approach 1

[0034] Specific embodiments Specific embodiment one: combination figure 1 To explain this embodiment, an ontology-based travel information recommendation method in this embodiment specifically follows the following steps:

[0035] Step 1. Construct the ontology of tourist attractions;

[0036] Step 2: Use FP-Growth algorithm to mine association rules between users;

[0037] The FP-Growth algorithm is a frequent pattern growth algorithm;

[0038] Step 3: Use the threshold of association rules to divide users into 2 categories, one is associated users, and the other is irregular users; the threshold is set manually;

[0039] Step 4. Use the collaborative filtering algorithm that incorporates the time factor and the evaluation factor into the associated users to generate scenic spot recommendations;

[0040] Step 5: Use a collaborative filtering algorithm based on tourist attractions ontology for irregular users to generate attractions recommendations;

[0041] Step 6. Combine the tourist a...

specific Embodiment approach 2

[0044] Specific embodiment two: this embodiment is different from specific embodiment one in that the tourist attraction ontology is constructed in the first step; the specific process is:

[0045] Step 1: From N articles (for example: Feng Xin, Wang Chengliang. Application research of ontology in tourism information system [J]Computer and Modernization.2010(3):128-133.

The attraction ontology obtained in [J]Information Technology.2013(2):135-140.) is imported into the tourist attraction ontology to be constructed, and N Documents are merged; in the process...

specific Embodiment approach 3

[0058] Specific embodiment three: this embodiment is different from specific embodiment one or two in that: the structure of the tourist attraction ontology is a tree structure, the nodes between the upper and lower levels have a clear parent-child relationship, and each node is a separate individual , There is no intersection with other nodes in the same layer.

[0059] The node is the type of tourist information involved in the tourist attraction, for example, the tourist attraction contains: transportation, accommodation, food, etc.

[0060] Other steps and parameters are the same as those in the first or second embodiment.

Abstract

An ontology-based travel information recommending method is provided, and aims to solve the problems that existing travel recommending results are inaccurate, and recommendations are staticized; the method comprises the following steps: 1, building a travel sight spot ontology; 2, using a FP-Growth algorithm to excavate association rules between users; 3, using an association rule threshold value to split users into associated users and random users; 4, applying the cooperation filtering algorithm combining time factor and evaluate factor to associated users, thus forming sight spot recommendations; 5, applying the cooperation filtering algorithm based on the travel sight spot ontology to random users, thus forming sight spot recommendations; 6, combining the travel sight spot recommending results of step 4 and 5; 7, carrying out contextual information filtering for the combined result; 8, using the filtered result for information development based on the travel sight spot ontology. The ontology-based travel information recommending method is applied to the travel information recommending field.

Description

Technical field [0001] The invention relates to an ontology-based recommendation method for travel information. Background technique [0002] Nowadays, people's living standards continue to improve, and the ways of leisure and entertainment have become diverse. The original monotonous leisure methods are far from meeting the needs of modern people. Therefore, tourism conforms to the tide of development of the times and is integrated into everyone's life, becoming an important way of leisure and entertainment. The Internet is an important channel for people to obtain travel information, but the huge amount of travel information makes tourists lost in the ocean of information. Therefore, how to solve the information overload and make accurate tourism information directly into the eyes of tourists is the biggest problem. Therefore, travel information recommendation came into being. [0003] The recommendation system appeared in the 1990s. The existing recommendation technologies m...
